Why You’ll Love This Lasagna Soup

• Easy – This recipe is super easy to make all in one pot!
• Tastes like lasagna – This soup is loaded with all the classic flavors you’d expect in lasagna… it’s meaty, cheesy and has a rich marinara broth.
• Filling and comforting – Packed with protein, pasta and a variety of cheeses this soup is a well-rounded meal that’s filling, cozy and sure to satisfy.

Ingredients Needed

• lasagna noodles – you’ll need 10 lasagna noodles that you’ll break up before adding to the soup. Make sure you grab regular lasagna noodles and not no boil noodles.
• Italian sausage – I used sweet Italian sausage, which adds a ton of flavor to this soup, but feel free to use hot Italian sausage if you want more of a kick. Ground beef would also be a delicious option and is often found in lasagna. For a lighter option use ground turkey or Italian chicken or turkey sausage instead.
• yellow onion and garlic cloves – two essential ingredients that add a ton of flavor to this soup.
• red bell pepper – diced and chopped for a touch of sweetness. Feel free to use any color bell pepper.
• tomato paste – helps to thicken the soup. Pro tip! If you have leftover tomato paste scoop tablespoons of the paste onto a parchment lined baking sheet and freeze. Once solid transfer to a freezer-safe bag and store for later use. You can watch my tomato paste hack video if interested.
• pasta sauce or marinara – this is the main component of the broth, giving it that lasagna-like taste. I love Rao’s marinara sauce, but homemade or your favorite store-bought brand will work.
• diced tomatoes – to add more tomato flavor. I recommend using diced San Marzano tomatoes for the best flavor. My favorite brand is the Muir Glen Organic Diced San Marzano Style Canned Tomatoes. Feel free to use crushed tomatoes if that’s what you have on hand.
• veggie or chicken broth – the liquid base of your soup. I recommend using low sodium broth so you can control the sodium amount in your soup.
• cottage cheese – for some added protein and creaminess we’re blending the cottage cheese with 1 cup of the marinara sauce then adding it to the soup. If you don’t have cottage cheese or aren’t a fan you can use ricotta cheese instead. If using ricotta, no need to blend it before adding to the soup since it’s already smooth and creamy.
• seasonings – we’re using Italian seasoning, ground black pepper and crushed red pepper flakes. Feel free to skip the red pepper flakes if you’re not a fan of spice or if you’re serving this to kiddos.
• olive oil – to sauté the vegetables and create a flavorful base.
• balsamic vinegar – for a subtle tangy sweetness.
• baby spinach – you can never go wrong with more veggies!
• mozzarella and parmesan cheese – for that cheesy, melty topping.
• fresh basil – I love adding fresh herbs to my recipes and fresh basil is the perfect pairing for this lasagna soup. Fresh parsley would also be a good herb for this soup.

How to Make Lasagna Soup

This lasagna soup recipe is way easier to make than traditional lasagna. No layering of noodles, sauce and cheese. Just cook everything up in one pot and enjoy! Here’s how to make it:

Step 1: Heat the olive oil in a large pot over medium heat, then add the onion and red pepper and sauté for 5-7 minutes, until softened. Add the minced garlic and sauté for a few more minutes.

Step 2: Next, add the Italian sausage, Italian seasoning, black pepper and red pepper flakes. Cook for 7-10 minutes until the meat is browned and cooked through, breaking it up as it cooks.

Step 3: Stir in the tomato paste, then add pasta sauce, diced tomatoes and broth. Bring to a boil.

Step 4: Once boiling, add the noodles then reduce heat to a simmer and cook for 15-20 minutes until noodles are tender.

Step 5: While noodles are cooking blend the remaining pasta sauce with the cottage cheese until smooth.

Step 6: Add the blended cottage cheese mixture, spinach and vinegar to the pot. Simmer for 2-3 minutes until the spinach wilts.

How to Serve Lasagna Soup

Serving this soup is the best part! Ladle thee soup into bowls and top with fresh mozzarella, parmesan and fresh basil! Stir in the cheeses so they melt and dig in! This soup is plenty filling on its own, but if you want to serve it with some sides, here’s some excellent options:

• Bread on the side: Nothing pairs with soup quite like a slice of warm bread. Try it with some homemade sourdough bread or garlic knots to scoop up every last bite.
• Salad pairing: Lighten things up with a simple salad. My kale caesar salad, arugula salad, or easy cucumber salad would be a great addition to keep the meal balanced while adding a fresh crunch.
• Veggie boost: For an extra pop of flavor, add some extra veggies to the side like air fryer brussels sprouts or roasted asparagus for a little extra bite and variety.

How to Store Lasagna Soup

• In the refrigerator: Allow the soup to cool to room temperature before storing. Transfer the soup to airtight containers and refrigerate for 4-5 days.
• Reheating: Reheat on the stove over medium heat. Thee soup will likely thicken as the noodles soak up some of the broth while sitting, so you might want to add a touch more broth or water while reheating.
